Abstract

A 53-year-old Korean female patient with partially edentulous mandible caused by the removal of her long bridge from the left lower lateral incisor to the left second molar, was planned for the implant fixture installation. After 3-dimensional computed tomographical scanning was transferred on OnDemand3Dⓡ (Cybermed Co., Seoul, Korea) software program for the virtual planning, MK III Groovy RP implants of Braenemark Systemⓡ (Nobel Biocare AB Co., Goeteborg, Sweden) were installed by using of In2Guideⓡ (CyberMed Co., Seoul, Korea) surgical template with Quick Guide Kitⓡ (Osstem Implant Co., Seoul, Korea) system. Fixture installations were successful for virtual planning without any complications, such as inferior alveolar nerve damage, malpositioning, and infections. Postoperative computed tomographic scans were aligned and fused to the planned implant, and the mean angular deviation between planned and actual implant axes was 2.665°± 1.910°, the mean distance between planned and actual implant at neck area was 0.975 mm ± 0.247 mm, horizontally, and 0.652 mm ± 0.502 mm, vertically. The average distance between planned and actual implant at apex area was 0.700 mm ± 0.383 mm, horizontally, and 0.600 mm ± 0.467 mm, vertically. Implant fixture installation with surgical guide from virtual planning on the 3D image program was revealed as the precise and trustable method with higher accuracy of distance difference lower than 1.0 mm and of angular deviation lower than 3.0°.
